Constructor Detail

### POPOSigningKey

    public POPOSigningKey(POPOSigningKeyInput poposkIn,
                          AlgorithmIdentifier aid,
                          ASN1BitString signature)

  Creates a new Proof of Possession object for a signing key.

Parameters:
  `poposkIn` - the POPOSigningKeyInput structure, or null if the CertTemplate includes both subject and publicKey values.
  `aid` - the AlgorithmIdentifier used to sign the proof of possession.
  `signature` - a signature over the DER-encoded value of poposkIn, or the DER-encoded value of certReq if poposkIn is null.

Method Detail

### getInstance

    public static POPOSigningKey getInstance(java.lang.Object o)

### getInstance

    public static POPOSigningKey getInstance(ASN1TaggedObject obj,
                                             boolean explicit)

### getPoposkInput

    public POPOSigningKeyInput getPoposkInput()

### getAlgorithmIdentifier

    public AlgorithmIdentifier getAlgorithmIdentifier()

### getSignature

    public ASN1BitString getSignature()

### toASN1Primitive

    public ASN1Primitive toASN1Primitive()

  POPOSigningKey ::= SEQUENCE { poposkInput [0] POPOSigningKeyInput OPTIONAL, algorithmIdentifier AlgorithmIdentifier, signature BIT STRING } -- The signature (using "algorithmIdentifier") is on the -- DER-encoded value of poposkInput. NOTE: If the CertReqMsg -- certReq CertTemplate contains the subject and publicKey values, -- then poposkInput MUST be omitted and the signature MUST be -- computed on the DER-encoded value of CertReqMsg certReq. If -- the CertReqMsg certReq CertTemplate does not contain the public -- key and subject values, then poposkInput MUST be present and -- MUST be signed. This strategy ensures that the public key is -- not present in both the poposkInput and CertReqMsg certReq -- CertTemplate fields.

  Specified by:
    `toASN1Primitive` in interface `ASN1Encodable`
  Specified by:
    `toASN1Primitive` in class `ASN1Object`
  Returns:
    a basic ASN.1 object representation.
